One rainy night, a speeding black sedan clips his car. Enraged, Jang gets out to curse the driver—only to be stabbed three times in the chest by a pale, smiling stranger. The "Devil" (Kim Sung-kyu) is a serial killer who chose the wrong monster to hunt.
Two are in cages. One is free. The report’s final line? There is no justice. Only the balance of monsters.
While fictional, The Gangster, The Cop, The Devil taps into a grim reality. In several Latin American and Asian nations, authorities have admitted to off-the-books alliances with former cartel members to capture even more violent terrorists or rival assassins. It’s the “enemy of my enemy” paradox: when the state admits it cannot protect its citizens, it sometimes deputizes the very people it is trying to imprison. the gangster the cop the devil
Played by the charismatic powerhouse Ma Dong-seok (Don Lee), Jang is a brutal but principled crime boss. He is the "immovable object" of the underworld until he becomes the target of a random attack by a serial killer.
But the last shot is of Jang Dong-soo in his cell, doing push-ups, smiling. He knows the cop owes him a favor. He knows his reputation is untouchable—he survived the Devil. And he knows that outside, the inspector is already looking at the next case, realizing that without his criminal partner, he is just a man with a badge.

Usually, the "enemy of my enemy is my friend" trope feels lazy. Here, it feels necessary. The film cleverly strips away the bureaucratic red tape. The Cop cannot catch the Devil because the law is slow; the Gangster can catch the Devil because he acts outside the law, yet he needs the Cop to legitimize the capture.
When Jung learns that the tough-guy gangster Jang was stabbed, he smells opportunity. He doesn’t want to save Jang. He wants to use him as bait. Two are in cages
Watching a detective navigate the ethics of using a criminal syndicate to solve a case provides a fascinating look at the "gray area" of justice. The film poses a cynical but intriguing question: Is a "bad guy" who follows a code better than a "madman" who follows none? Visuals and Action
It reminds us that sometimes, to catch a devil, you have to invite a gangster to the table.
What happens when the predator becomes the prey? What happens when a mob boss needs a cop to stay alive? You get an unholy trinity where trust is a weapon, revenge is the currency, and justice is just a word for whoever is left standing.
In the final frame, the gangster goes to prison. The cop gets a promotion. The Devil gets a life sentence. On paper, the system worked.
